The cable of a uniformly loaded suspension bridge hangs in the form of a parabola. The roadway which is horizontal and 100m long is supported by vertical wires attached to the cable, the longest wire being 30m and the shortest being 6m. Find the length of the supporting wire attached to the roadway 18m from the middle.

over the towers of a bridge a cable is hung in the form of a parabola,have their tops 30 meters above the road way are 200 meters apart.If the cable is 5 meters above the road way at the centre of the bridge,then the length of the vertical supporting cable 30 meters from the centre is

A horizontal wire 0*1m long having mass 3g carries a current of 5A . Find the magnitude of the magnetic field which must act 30^@ to the length of the wire inorder to support its weight.

IF the distribution of weight is uniform, then the rope of the suspended bridge takes the form of parabola.The height of the supporting towers is 20m, the distance between these towers is 150m and the height of the lowest point of the rope from the road is 3m. Find the equation of the parabolic shape of the rope considering the floor of the parabolic shape of the rope considering the floor of the bridge as X-axis and the axis of the parabola as Y-axis. Find the height of that tower which supports the rope and is at a distance of 30 m from the centre of the road.

A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:
